Spider對(duì)網(wǎng)站抓取數(shù)量突增往往給站點(diǎn)帶來很大煩惱，紛紛找平臺(tái)想要Baiduspider IP白名單，但實(shí)際上BaiduSpider IP會(huì)隨時(shí)變化，所以并不敢公布出來，擔(dān)心站長(zhǎng)設(shè)置不及時(shí)影響抓取效果。百度是怎么計(jì)算分配抓取流量的呢？站點(diǎn)抓取流量暴增的原因有哪些呢？

總體來說，Baiduspider會(huì)根據(jù)站點(diǎn)規(guī)模、歷史上網(wǎng)站每天新產(chǎn)出的鏈接數(shù)量、已抓取網(wǎng)頁的綜合質(zhì)量打分等等，來綜合計(jì)算抓取流量，同時(shí)兼顧站長(zhǎng)在抓取頻次工具里設(shè)置的、網(wǎng)站可承受的最大抓取值。

從目前追查過的抓取流量突增的case中，原因可以分為以下幾種：

1， Baiduspider發(fā)現(xiàn)站內(nèi)JS代碼較多，調(diào)用大量資源針對(duì)JS代碼進(jìn)行解析抓取

2，百度其他部門（如商業(yè)、圖片等）的spider在抓取，但流量沒有控制好，sorry

3，已抓取的鏈接，打分不夠好，垃圾過多，導(dǎo)致spider重新抓取

4，站點(diǎn)被攻擊，有人仿冒百度爬蟲（推薦閱讀：如何正確識(shí)別百度蜘蛛）

如果站長(zhǎng)排除了自身問題、仿冒問題，確認(rèn)BaiduSpider抓取流量過大的話，可以通過反饋中心來反饋，切記一定要提供詳細(xì)的抓取日志截圖。

【官方說法】只需兩步，正確識(shí)別百度蜘蛛（User-Agent）

步驟一：查看 User-Agent 信息在你的網(wǎng)站后臺(tái)查看日志或者使用網(wǎng)站統(tǒng)計(jì)工具，可以查到每次訪問你網(wǎng)站的 User-Agent 信息。百度蜘蛛的 User-Agent 格式如下： Baiduspider/數(shù)字（+版本信息）例如：Baiduspider/2.0、Baiduspider/2.0b等。步驟二：驗(yàn)證 IP 地址驗(yàn)證訪問你網(wǎng)站的 IP 是否是百度蜘蛛的 IP?？梢栽诎俣?/p>

我希望我的網(wǎng)站內(nèi)容被搜狗索引但不被保存快照，我該怎么做？

sogou spider遵守互聯(lián)網(wǎng)meta robots協(xié)議。您可以利用網(wǎng)頁meta的設(shè)置，使搜狗顯示只對(duì)該網(wǎng)頁建索引，但并不在搜索結(jié)果中顯示該網(wǎng)頁的快照。和robots的更新一樣，因?yàn)樗阉饕嫠饕龜?shù)據(jù)庫的更新需要時(shí)間，雖然您已經(jīng)在網(wǎng)頁中通過meta禁止了搜狗在搜索結(jié)果中顯示該網(wǎng)頁的快照，但搜狗搜索引擎數(shù)據(jù)庫中如果已經(jīng)建立了網(wǎng)頁索引信息，可能需要二至四周才會(huì)在線上生效。

百度搜索引擎基礎(chǔ)知識(shí)

威海Spider 威海Baiduspider
736

百度搜索引擎是中國最大的搜索引擎之一，它的基礎(chǔ)知識(shí)包括如下幾點(diǎn)： 1. 檢索方式：百度搜索引擎是基于關(guān)鍵詞的檢索方式，用戶輸入關(guān)鍵字進(jìn)行查詢，百度會(huì)通過算法分析索引庫中的信息，并以相關(guān)度排序呈現(xiàn)給用戶。 2. 搜索排名：百度的搜索結(jié)果排名是按照一系列算法計(jì)算出的，在搜索結(jié)果頁面中，排名越靠前的頁面一般來說被認(rèn)為是相關(guān)度更高的頁面。 3. 網(wǎng)頁收錄：百度會(huì)通過網(wǎng)絡(luò)爬蟲程序收集并存儲(chǔ)互聯(lián)網(wǎng)上的信
